• These salts, chemicals and accessories are essential for setting up the tank's mineral solution at the correct density for floating and for maintaining the strict standards of hygiene which will give the solution a long lifespan.
• Very little maintenance effort is required, less than for a swimming pool. No technical knowledge is required; the Apollo^tm ELV owners manual contains all the information you will need, presented in a way that is easy to follow.
• If properly looked after, the solution should have a lifespan of 1 to 2 years.

Epsom Salts
 

• 350kg of Epsom Salts are added to water to give the optimum density or specific gravity of 1.28. This creates a 25% saturated salt solution, five times denser than sea water, which allows anyone - whatever their body weight - to float effortlessly and comfortably with their face clear of the surface.
• The remaining salt is used to top up the solution over time because some salt is lost during each float session.

Chemical Start-Up and Maintenance Kit
 

• The high salt concentration itself creates a powerfully sterile and hygienic environment. As a further safeguard, however, bromine is used as a sanitising agent and - like a swimming pool - the alkalinity and pH of the solution should be kept within well-established limits through simple periodic checks.
• This Start-Up Kit contains all the chemicals and test equipment needed to keep the solution sparkling fresh at all times and to satisfy even the most stringent environmental health standards.
• Ultra-violet light sterilisation is also available upon request.

Spare Filter Element
 

• After each float session the solution is purified by a powerful industrial filtration system which removes organic contaminants. In a 20 minute filtration cycle the contents of the tank are circulated twice, ensuring a level of hygiene far higher than can be found even in a well-maintained private swimming pool or spa.
• The filter element should be removed and cleaned regularly. Having a spare element as back-up means that there is no down-time for maintenance and the tank can stay in continuous use.

Ear Plugs, 200 Pairs
 

• Prevents water from entering the ears during a float session, which can be a source of irritation to some people.
• The use of ear plugs is entirely a matter of personal preference. We recommend that where a tank is used commercially, ear plugs should be available for those who wish to use them.
